LEAP 15.1 monitor failure.

This is regarding Machine #1 using a Samsung 27" Monitor with a 60Hz refresh rate.

Yesterday I was playing a small older 2D game through Wine. [nostalgic]
When I exited the game my monitor had changed from 1920x1080 to 1280x720.
I fixed this by going to Settings>>Display and Monitor and changing it back to 1920x1080.
Refresh rate was set to Auto.
The Samsung monitor reverted to 1920x1080 and all appeared to be fine.

Played the game again today and while I was playing the game there appeared to be a gauzy film
that crept up over the display and the task bar panel was jumping a bit.
I exited the game and because the screen was so fuzzy I rebooted.
The gauzy film started before openSuse started, while still on the Asus boot page.
I also shutdown the monitor and restarted it, but it is still the same.
I got in touch with Samsung and it appears the monitor is toast.

My questions are: Is it possible that playing that old game had anything to do with the monitor failure [because it is only 1280x720] as opposed to 1920x1080]?
I would hate to kill a brand new monitor. Is there some additional setup required to play this game at 1280x720 that I should be doing before I play?

Advice please.
